For chatting, we recommend a chatmail relay instead of a classic email provider.
If you run your own mail server, the most reliable way to make it
work with email clients is to publish an
autoconfig file
at
/.well-known/autoconfig/mail/config-v1.1.xml on your domain.
To set up a profile with a third-party classic email provider, you may need the "advanced settings" during profile creation. Please consult your provider for the required server settings.
Posteo

To use your Posteo email address you have to generate a specific password for it. Here is a guide on how to do that (also in German and Spanish): https://posteo.de/en/help/app-passwords
